The high-end tools like Segue SilkPerformer or RSW e-Test will run you about USD$35,000 or so. If that's not in the budget there's a freebie from Microsoft called WCAT that's not too bad, ZD has one in their benchmark suite, and there is a pile of open-source and Java tools as well. Do a search on freshmeat.net for "web stress test" and you'll find a bunch. http://www.testingstuff.com also has links to a few dozen testing tool vendors. What you do with most of them is create some test scripts and then let them run while varying things like the number of simultaneous requests, timings between requests, simulated connection speeds and randomizing terms in database lookups and so on. Or you'd run them at increasing load levels to get some benchmark data you can use to spot bottlenecks in the system or use in conjunction with your traffic logs to tell you when it's time to add more hardware. SilkPerformer lets you record a browser session that you perform manually and use that as a starting point for an automated script. You then add in various randomizing elements to try to simulate real-world load. It has software agents that can be installed on a number of client workstations that all report their data to a central test controller/server for aggregation and reporting. MSFT's WCAT can import existing log data to determine popular paths through a site and use that info to create test scripts.
